About User Security Each Oracle database has a list of valid database users. To access a database, a user must run a database application, and connect to the database instance using a valid user name defined in the database. Oracle Database enables you to set up security for your users in a variety of ways. When you create user accounts, you can specify limits to the user account. You can also set limits on the amount of various system resources available to each user as part of the security domain of that user. Oracle Database provides a set of database views that you can query to find information such as resource and session information. This chapter also describes profiles. A profile is collection of attributes that apply to a user. It enables a single point of reference for any of multiple users that share those exact attributes. Another way to manage user security is to assign users privileges and roles. Chapter 4, "Configuring Privilege and Role Authorization" provides detailed information.
